TORONTO — Ontario Provincial Police say members of its Criminal Investigation Branch will probe the death of a 15-year-old Toronto student who drowned while on a school trip to Algonquin Park last month.

Jeremiah Perry disappeared under the water after going for an evening swim in a lake with other students in early July. His body was discovered about a day later by the OPP’s underwater rescue unit.

Last week, the Toronto District School Board said Perry had not passed a swim test required to go on the trip, and apologized to the teen’s family.

The board’s director of education, John Malloy, said that of the 32 students who went on the multi-day canoe trip, 15 had failed the swim test.

Malloy said that the initial swim test took place in a lake, and that students who did not pass the first test should have been required to take a second test at C. W. Jefferys Collegiate Institute, the school Perry attended. But, he said, the second test was neither provided nor offered.
